Need to know level of confidence of perp being hispanic in order to eliminate other enthic possibilities/false positive - like "definitely hispanic" or "could be hispanic could be Filipino" or whatever.
pay attention to neighborhoods of perp ethnicity - do they cluster? Dense cluster? DMV records deep five for Worcester county. Media needs to carry this big time in the greater Worcester area. Just keep carrying the news. This case will be solved I believe.
dates and times of prior assaults: perhaps we can determine if perp holds a 9-5 job vs night job etc. do a teardown of what his likely profession is.
Some great thoughts, Cem. I see you have found out that Worchester has a big Hispanic population.
Given LE's statement, I'd guess their level of confidence that he's a light skinned Hispanic is pretty darn high. And the DNA phenotyping appears to be corroborating evidence, not sole evidence.
Excellent thought on the day of wk/time of day and work schedule bit. I had same one back when ForensicMass originally posted on the two attempted abductions. I'm sure the first two incidents occurred during a weekday and around midday. Just checked -- yes, they occurred on a Thursday -- first one around 10:30 am and the second one soon after while LE was investigating the first one. (Yes, extremely brazen!)
Vanessa's killing happened during a Sunday, so nothing the days of the week tell us re: a work schedule. But the first two incidents occurring midday on a weekday do *suggest* that those perps (two involved in one incident) don't work work more typical 9-5 jobs. Of course, there are days off and the like, but I'd still go with evening jobs or unemployed.
